Stink Bug or Boxelder Bug?
Many Alberta homeowners call every bug on their wall a “stink bug.” Before we treat, we confirm what you have, because the right treatment depends on it.
- Stink bug: Brown or grey, shield-shaped, smells when crushed.
- Boxelder bug: Black with red or orange lines, slimmer body, collects on sunny walls and near maple trees. See our boxelder bug control service.

Signs You Have Stink Bugs
The signs are easy to spot in fall and on sunny winter days.
- Groups of bugs on sun-facing walls, doors and window frames.
- Slow bugs crawling on curtains, windowsills and light fixtures.
- A sharp, herb-like smell after one is crushed.
- Dead bugs collecting on sills.
- Chewed or spotted fruit and vegetables in the garden.
Why Do I Have Stink Bugs?
They aren’t coming in for food or because your home is dirty. They want a warm, dry place to wait out winter.
- Gaps around windows, doors, siding, soffits and vents.
- Sun-exposed walls that draw them in on mild days.
- Gardens, fruit trees and shrubs nearby.
- Leaf litter and debris against the foundation.
Where Do Stink Bugs Hide?
Once they’re in, they tuck into tight, undisturbed spots and stay there until spring.
- Attics and wall voids
- Behind siding, trim and window casings
- Around door frames and garage walls
- Behind curtains, baseboards and light fixtures
- Under garden debris, bark and woodpiles
Are Stink Bugs Harmful?
Not to you or your home, but they’re a real nuisance.
- They don’t bite, sting or spread disease.
- They don’t damage the structure or breed indoors.
- Crushing one leaves a smell and sometimes a stain.
- In the garden, they can scar fruit and vegetables.
How to Prevent Stink Bugs
Late summer is the best time to do this, before they start looking for shelter.
- Seal gaps around windows, doors, siding and vents.
- Repair torn screens and worn weatherstripping.
- Clear leaves, wood and debris from beside the foundation.
- Vacuum them up. Don’t crush them.
DIY sealing helps, but high rooflines and soffits are hard to reach, and store-bought sprays only hit the bugs you can see.
How Much Does Stink Bug Control Cost?
Stink bug control at Major Pest Control starts at $495. The final price depends on your home’s size, where the bugs are gathering, and how bad the problem is. See our pest control costs page for more detail. A free inspection gives you the exact number. We serve Edmonton, Calgary and Red Deer.

FAQs About Major Pest Control Services
Vacuum the ones you see, then seal the gaps they use to get in. Store-bought sprays only kill what they touch. For lasting results, a professional exterior treatment in late summer, before they move in, stops them at the source.
They’re looking for a warm, sheltered place to wait out winter. Gaps around windows, siding and vents let them in, and sunny walls draw them close. Cluster flies do the same thing, so see our cluster fly control service if you’re also seeing flies on windows.
No. They don’t bite, spread disease or damage your home. The main problems are the smell when they’re crushed and, outdoors, scarred fruit and garden vegetables.
Stink bugs are brown or grey and shield-shaped. Boxelder bugs are black with red or orange lines and have a slimmer body. Both gather on sunny walls in fall, and you treat them the same way.
Vacuum them up gently or sweep them into a cup of soapy water. Crushing or swatting them releases the odour. Empty the vacuum outside right away.
